[编程入门]完数的判断-题解（C语言代码）

解题思路:

注意事项:

参考代码:

#include <stdio.h>

    int main ()

{

    int N;

    int i,j,k;

    int sum=0;

    scanf("%d",&N);

    for(i=2;i<=N;i++)

    {

        for(j=1;j<=i/2;j++)

        {

            if(i%j==0)

            {

                sum+=j;

            }

        }

        if(sum==i)

        {

        printf("%d its factors are ",i);

            for(k=1;k<=i/2;k++)

            {

                if(i%k==0)

                {

                    printf("%d ",k);

                }

            }

            printf("\n");

         }

    sum=0;

    }

    return 0;
